Kevin, another method of slowing down an AC fan is to put a capacitor in series with the AC leads as a voltage dropping element.
A local Ham played with this idea many years ago and as I recall he started with a 1 Mfd paper capacitor. In his case he dropped the voltage to around 90 volts to the fan. 73 John VE3AMZ ----- Original Message ----- From: Kevin Custer To: Repeater-Builder@yahoogroups.com Sent: Sunday, December 21, 2008 8:58 PM Subject: Re: [Repeater-Builder] Re: fan timer circuit n...@no6b.com wrote: One reason why I've dismissed using any switching on my 110 V cooling fans & let them spin 24/7. I have used 220 V muffin fans on 110 V and they last for years. I put one in service in 1997, and it's still turning. Kevin
